Answer 3

no @Ilovecake

Answer 4

Help anyone?

Answer 5

Standard form will be something like a+bi

Answer 6

Been a whole since I converted them... as long as you used the proper formula based on the Euler relationship it should come out right.

Answer 7

The radius times the cosine is the real part and the radius times the sone is the imaginary part.

Answer 8

So at 5pi/6 we have \(\left(-\dfrac{\sqrt{3}}{2},\dfrac{1}{2} \right)\) Multiply the 4 through that and you get: \(\left(-\dfrac{4\sqrt{3}}{2},\dfrac{4}{2} \right)=\left(-2\sqrt{3},2 \right)\), so you will use those for your cos and sin.

Answer 9

Do you see how I am getting that?

Answer 10

I think so

Answer 11

Which that tells me 4squart(3) + 4i is not quite right. You are at double the values because of the canceling the half as shown in what I did.
